Hi,
I lay down the Saran Wrap so that it floats on top (in contact) of
the solution and hopefully cuts all contact with the air.
OK. I wonder if anyone has tested the wrap to see how permeable it is to
oxygen.
I do not know about Saran Wrap, but a friend of mine used to work at a
chemical plant belonging to a company that had been in business well
over 100 years. They made plastic film, such as Cellophane and similar
ones used for dielectrics in capacitors. Once a worker got so pissed off
he tossed the disc from a floor polisher into the mixer. It was one made
of steel wool. My friend thought that pretty funny, considering that all
the capacitors made from that lot would be shorted out.
